Abstract:
To provide a bathtub washing system capable of preventing hot water at an abnormally high temperature from being jetted from a washing nozzle even when a hot water filling valve has an opening defect when a temperature of hot water introduced from a heat source machine is at a prescribed temperature or higher.SOLUTION: A bathtub washing system 1 includes: a hot water filling valve 32 which opens/closes a hot water supply path 60 guiding hot water heated by a heat source machine 4 to a washing nozzle 21; a controller 5 which opens the hot water filling valve, jets hot water from the washing nozzle, and controls bathtub washing operation; temperature detection means 51 which detects a temperature of hot water in the hot water supply path; a water supply passage 70 whose downstream end is connected to the hot water supply path and which flows water to be supplied by the water supply source into the hot water supply path; a water filling valve 71 which opens/closes the water supply passage; and notification means. The controller closes the hot water filling valve to stop the execution of the bathtub washing operation, notifies abnormality by the notification means, opens the water filling valve, and flows water into the hot water supply path when the temperature detection means detects a temperature of hot water at a prescribed temperature or higher during the execution of the bathtub washing operation.SELECTED DRAWING: Figure 1
